Porcelain Tile / September 14, 2018 / Brousseau
Ensure that scrap tiles or another similar material is placed under the tile that is being drilled. This will help to halt the progress of the drill once it has finished drilling through the tile. Before drilling tile ensure that you are wearing the correct safety equipment including safety glasses or goggles. Ensure that you are using a residual current device (RCD) to help prevent electric shock. Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores. Mark the center of the hole to be drilled into the tile by using a marker or a sticky drive pad.
These methods will not keep the drill bits cool enough and will drastically shorten the life of the drill bit. Ensure that the drill is in normal mode and set the drill to between 1000 and 1500 rpm. If you have marked the tile with a marker it is best to drill into the tile using a method called leaning in. Leaning in ensures that the drill will not slip and wander off center as you begin to drill into the tile.
Simply start the drill in a vertical position and the sticky pad will ensure that the drill does not slip. Once you have finished drilling the tile simply peel off the sticky drive pad. Because the majority of small diameter holes will be cut into tiles already fixed to the wall it will be necessary to drill a fixing hole behind the tile. Replace the diamond core with the appropriately sized masonry drill bit and set the drill to hammer mode. Use a slow speed for drilling into hard materials to ensure that the tip doesnt overheat. Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
